SRAM DualDrive 3-Speed Left Trigger Shifter

SRAM's DualDrive is a unique drivetrain that combines a three-speed internal-gear hub with an external cassette and derailleur. The result is a wide-range of gears in a clean, easy-to-control system. The DualDrive 3-Speed Left Shifter features a thumb trigger that controls gear changes in the internal hub (sold separately).
